A novel non‐circulating‐current magnetic‐integrated three‐bridge dual‐buck inverter (DBI) is proposed. By adding the third bridge, the proposed inverter can remove two input capacitances and enhance the utilisation of input voltage in traditional dual buck half‐bridge inverter (DBHBI). In addition, the partly coupled inductors with non‐dotted ends connected are applied to elevate the power density. The dc link diode is utilised to eliminate circulating current caused by magnetic induction absolutely. The generating principle of circulating current and operating principle of the proposed inverter have been analysed in detail. Finally, experimental results are obtained on a 1 kW prototype to verify the practical application of the proposed inverter.
